(iii) Class C shares not paid in by those involved in the Shared Ownership Program in exercise of their original preemptive rights, due to failure to exercise such right or to an assignment thereof, shall be allocated to those participating in such program provided that they have paid in class C shares and stated their intention to exercise their residual preemptive rights. The remaining shares shall be converted into class D shares and shall be offered to shareholders of that class willing to exercise their residual preemptive rights with respect to non-paid in class C shares;

(iv) Class D shares not paid in exercise of the preemptive rights attached to that class of shares shall be allocated to those who have paid in such class of shares and stated their intention to exercise their residual preemptive rights;
